1. Assemble the reducing valve.
Install the secondary pressure setting spring and the spring seat
in that order on the spool, then press the spring seat down and
install the two half-circle shaped pieces of washer 1 on the
spring seat so they don't overlap.
NOTE
• Face washers 1 edge side up so they catch the head of the
spool.
• Do not depress the spring seat more than 4 mm (0.16 in.).
• The metal washer 2 is not used in the photo at left.
• The thickness of washer 2 varies for each spool due to the
preset adjustment of the secondary pressure spring.
